FISCHER-TROPSCH SYNTHESIS |
| 摘要 |
A process (10) to produce Fischer-Tropsch products includes feeding feed synthesis gas (30) with a substantially constant target feed synthesis gas H2/CO ratio to a Fischer-Tropsch synthesis stage (16). A portion of the feed synthesis gas (30) is converted to Fischer-Tropsch products in the Fischer-Tropsch synthesis stage (16). The Fischer-Tropsch products (20) from the Fischer-Tropsch synthesis stage (16) are withdrawn. A Fischer-Tropsch synthesis stage tail gas (26) which includes unconverted H2 and CO is obtained. The operating conditions of the Fischer-Tropsch synthesis stage (16) are manipulated to achieve a substantially constant target tail gas H2/CO ratio, with the target tail gas H2/CO ratio being substantially different from the target feed synthesis gas H2/CO ratio. |

1. A process to produce Fischer-Tropsch products, the process including
feeding feed synthesis gas with a substantially constant target feed synthesis gas H2/CO ratio to a Fischer-Tropsch synthesis stage; converting a portion of said feed synthesis gas to Fischer-Tropsch products in the Fischer-Tropsch synthesis stage; withdrawing said Fischer-Tropsch products from the Fischer-Tropsch synthesis stage; obtaining a Fischer-Tropsch synthesis stage tail gas which includes unconverted H2 and CO; and manipulating operating conditions of the Fischer-Tropsch synthesis stage to achieve a substantially constant target tail gas H2/CO ratio, said target tail gas H2/CO ratio being substantially different from the target feed synthesis gas H2/CO ratio. |
